Book box 00221. Digital files for manufacturing products on a laser machine (co2 or diode).
A large book with an A4 inside. One of the simplest books I have drawn, yet very durable thanks to the multi-layer cover and stiffening ribs in the spine.
The only extra parts are 2 optional magnets. Add your own text on the spine, or engrave a description or map inside the cover.
The inside is flat with one protrusion, the magnetic lock. Your laser needs at least 400 × 300 mm; it takes 4 sheets of 500 × 300 mm.
The magnetic lock needs 2 magnets 3 mm wide, no thicker than the material.
